To all whom it may concern:

Be it known that I, JOHN J. STOPPLE, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Baling-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in baling-presses.

The object of the invention is the provision of means for facilitating the compression of material for forming a bale.

lVith this and other objects in view the invention consists of certain other novel constructions, combinations, and arrangements of parts, as will be hereinafter f1'1ll;, described, illustrated in the accompanying drawings, and more particularl; pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a mechanism constructed in accordance with the present invention. Fig. 2 is a longitudinal vertical sectional view of the liechamsm depicted 1n Fig. 1. Fig. 3 1s a fragmentary horizontal sectional view of the framework of the press, showing the pivoted retainers or dogs in position thereon. Fig. 1 is a view of the guiding means for the draftcable, partly shown in front elevation and transverse section. Fig. 5 is a perspective view of the bracket which supports the guide pulley or sheave. Fig. 6 is a transverse sectional view of the framework, showing the bracing means for the links upon which the lever is fulcrumed.

Referring to the drawings by numerals, 1 designates the parallel sled-runners, upon which is mounted a framework 2. The framework 2 is of any preferred structure and is provided with a compression-chamber, within which is positioned a plunger 3. A plate 4 is pivotally secured at its lower end to the plunger 3 for closing the bottom of the hopper 5 when the plunger is at the limit of its compression-stroke.

A lever 6 is pivoted near its lower end, as at 7, to the plunger 3 and is fulcrumed, as at 8, upon the upper ends of links 9 9, which links are preferably pivotally mounted upon a transverse rod or shaft 10, carried upon the sides of theframework 2. The rod 10 is preferably j ournaled in annular members or coli l I l l l I l l I l J g f l l a l i 1 l l l l l I l lars 10. These collars 10 are carried by the sides of the framework 2. It has been found desirable to brace the links 9 9. This is ac complished by preferably emplo ing crossed braces 9 9, each one of which is secured at its upper end to one of the links and at its lower end to the opposte link. The braces 9 prevent any wabbling or lateral movement of the lever.

A yoke 11 is pivotally mounted, as at 12, upon the sides of the framework 2. The yoke is preferably an inverted substantially U-shaped structure. I preferably employ a pair of springs 1.2 for connecting the upper portion of the yoke 11 to the links 9. Each spring 12 is connected at end to the yoke 11 and at its opposite end to one of the links 9, near the lever 6. The yoke 11 may be adjusted forward (see arrow, Fig. 1) for tensioning the springs 12 by positioning transverse fastening meansas, for instance, bolts 13in the apertures 14 of the brace bars or rods 15, which are pivotally connected to the sides of the yoke 11, as at 16. It will therefore be obvious that the adjustable braces 15 constitute adjusting means for the yoke 11 and tensioning means for the springs 12.

A horizontal shaft 17 is journaled in bearings 18. The bearings 18 are carried by the sides of the framework 2. A wheel 19, which is fixed to the shaft 17, is provided with a peripheral groove. Power-conveying meansas, for instance, cable 20-is secured, as at 21, in the groove of the wheel 19.

An. eccentric-disk 22 is fixed to the shaft 17. This eccentric-disk 22 is provided with a tangential arm 23 and a cut-out portion 24:. The outer end of arm 23 and the lever 6 are connected by suitable flexible meansas, for

instance, chain 25. By employing a hook 26, carried by lever 6, any slack in the chain may be taken up. The portion of the arm 23 and eccentric-disk 22 which is engaged by the chain 25 is grooved, as 27, so that the said oh or connecting means 25 may be seated witl'un said groove 27 as the lever 6 is moved downwardly for actuating the plunger 3. Upon referring to Fig. 2 it will be noted that the chain or connecting means 25 is positioned within the groove 27 and thereby preventing said connecting means from being removed off of said arm and eccentric. It has been found om practical experience that a material advantage is obtained by employing the arm 23 and securing the connectits upper or outer plate 28.

of shaft 17 should become Worn. The bracket for supporting the guide-pulley 33 is ing means at its outer end, as upon rotating the eccentric-disk the lever 6 Will be caused to rapidly descend at first, and as the resistance upon the plunger 3 increases, owing to the charge becoming more compressed, the leverage derived fromthe eccentric-d isk22 will increase as the lever 6 approaches its lowest position. It will therefore be seen that the lever 6 constitutes one lever means, while the eccentric-disk constitutes an auxiliary lever means, thereby producing progressive double-lever means for actuating the plunger 3 upon its compression-stroke.

1t has been found that the chain or other suitable connecting means 25 will stretch to a certain degree, and it often occurs that the operator fails to take up this slack, which if the eccentric-disk is not cut away, as at 24, will wreckthe machine, because the upper end of the lever 6 will be forced against the periphery of the eccentric-disk in its down- The plate 28 is secured against the bottom surface of the beam 35, while the flange 29 engages the outer longitudinal edge of the same. (See Fig. 5.)

A staking device for securing the press in a fixed position during the operation .of the same is employed. Said device comprises a pair of downwardly-extending parallel brakepins 36, which are pivotally connected, as at 37, Fig. 2, to the front end of the parallel sled-runners 1. The brake-pins are of suflicient length to engage the transverse beam 35 when said pins are sunk into the ground, the beam 35 limiting the pivotal downward movement of said pins. If the pivotal downward movement of these brake-pins was not limited, said pins would turn upon their pivots 37, permitting the press to pass or ride over the same, and subsequentlysaid ward movement, necessitated for the completion of the conipression stroke of the plunger 3. In my improved structure of the eccentric-disk 22 this liability of breaking or wrecking the machine is obviated, even if the slack of the chain is not taken up, as the cutaway portion 24 will not permit the upper end of the lever 6 to come in contact with the eccentric-disk, but will permit the arm 23 to bear down upon the upper edge of the lever, thereby stopping the draftanimal which i may be attached to the cable 20, for the lever 1 their points extending to the rear of the machine. The parallel pins are connected by a horizontal rod 38. A clevis 39 is secured to the beam 35, and attached to said clevis is preferably a chain 40, to which is attached a draft-animal for hauling the press. It will be obvious upon drawing chain 40 taut that the pins 36 will be liftedout of or from engagement with the ground, owing to the engagement of the rod 38 with said chain 40.

Referring particularly to Fig. 3, 1 form elongated slots or openings 41 in the frame work 2, and within each of these slots and pivotally mounted, as at 42, upon the framework is a retainer or dog 43. Each retainer comprises a substantially straight body provided with a curved portion 44, terminating in a straight rear extension 45, the extension 45 constituting a finger or arm, which extends substantially parallel with the body. Upon each body there is formed a tapering nose 46, projecting into the compressionchamber. Upon the body, opposite to the nose 46, is formed a head 47, which constitutes a stop that engages one side of the framework, thereby limiting the inward movement of the nose 46. For holding the nose 46 in the compression-chamber 1 cmploy suitable means "for exerting an outward 32, as Wlll be clearly seen in Fig. 4. The pressure upon the rear extension 45-as, for shaft 32 is of suflicient length to permit the instance, a flat spring 48, which is curved guidepulley to have a slight longitudinal I so as to engage tl..e inner face of the extenmovement thereon, if necessary, for coopersion 45. The spring is secured at one end to ating with the wheel 19, whose grooved pethe side of the framework, and its outer free 6 and the eccentric 22 are locked against fur ther movement.

Guiding means is employed for facilitating the positioning of the draft-cable in the peripheral groove of wheel 19. This guiding means comprises a bracket which is provided with a horizontal apertured base-plate 28, having a vertical flange 29 at one of its longitudinal edges. Parallel arms 30 are integral i with the flange 29 and plate 28. Each one of these arms is formed with an aperture 31 near its outer end, within which shaft 32 is positioned. These arms are curved for placing the shaft above the plate 28, thereby positioning the guide-pulley 33 above the said 1 The guide pulley or sheave 33 is provided with a bore or transverse aperture 34 of' sufficient diameter to permit said guide-pulley to freely revolve upon the shaft riphery is positioned within the grooved peend presses against the extension 45. It riphery of the guide-pulley 33. it will therewill be noticed that the noses 46 may be fore be obvious that the guide-pulley 33, forced outward by passing a division-plate owing to its overlapping a portion of the petoward the rear of the compression-chamriphery or rim of wheel 19, constitutes revoher; but as soon as the division-plate passes luble guiding means for the cable 20, said] the retainers or dogs the springs 48 will guiding means being capable of lateral moveforce the noses 46 into the compression chamment, which is necessary if the bearings 18 l her, while the head 47 will limit the inward preferably secured to a transverse beam 35.

pins would be drawn out of the ground with 7 LOO back to their normal movement of said noses. The plunger 3 is free to reciprocate within the compressionchamber past the retainers or dogs 43, for the reason that slots or grooves are formed upon the sides of the plunger registering with the similar openings 41 of the. framework The material being operated upon may be pressed past the said retainers or dogs by contact with the beveled surface 49, tne retainers or dogs swinging upon their pivots 42 to permit such passage, but being thrown position after such passage, preferably by means of the springs 48.

y employing the retracting-springs 12 and the arm 23 of eccentric-disk 22 the draftcable 20 is wound around the wheel 19 fast enough to take up any slack that occurs in said cable 20 during t e backing of the draftanimal preparatory for advancing to complete another stroke of the plunger 3. 3y the peculiar structure of the mecl anism said advantage is obtained, for it will be readily understood that if the mechanism worked slowly the swingletree and the slack in cable 20 would hit against the rear legs of the draft-animal and be likely to be broken by said animal stepping upon tie same. From practical experience this undesirable result and the slow operation of the press is obviated, as the cable 20 is practically taut at all times, for my mechanism works rapidly whether the lever 6 and links 9, constituting a toggle, and tlie eccentrics 22 are being operated or whether said members are moving from the position similar to that depicted in Fig. 2 to their normal position. illustrated in Fig. 1.

Uwing to the employment of the arm 23 upon t3 e eccentric, the lever 6 is moved down very rapidly at the start to take up the slack, and it throws a greater strain on the animal at the start than at e finish, thus equalizing t .e pull from start to finish.
